Definitions

  • the present application relates to the field of communications, and more particularly, to a method and terminal device for receiving feedback information.
  • the Hybrid Automatic Repeat reQuest (HARQ) feedback information uses the Physical Hybrid ARQ Indicator Channel (PHICH), the acknowledgment/negative acknowledgment (ACK/NACK) information is indicated by 1 bit, and the uplink HARQ of the LTE adopts a synchronous HARQ design, that is, the retransmission is performed at a fixed time relative to the initial transmission, and each PHICH corresponds to uplink data of one terminal device.
  • PHICH Physical Hybrid ARQ Indicator Channel
  • ACK/NACK acknowledgment/negative acknowledgment
  • the Physical Downlink Control Channel may also indicate a receiving state of the uplink data, for example, a New Data Indicator (NDI) carried in the uplink grant (Uplink grant) resource of the PDCCH indicates retransmission so as to identify the failure of uplink data demodulation, that is, using PDCCH to indicate retransmission is an "implicit" feedback.
  • NDI New Data Indicator
  • the implicit feedback method of using the NDI in the Uplink grant of the PDCCH to indicate uplink retransmission is further extended in the New Radio (NR) system.
  • NR New Radio
  • the current consensus is that the uplink HARQ and downlink HARQ both use asynchronous HARQ, the dedicated feedback channel of the uplink data, that is, PHICH, is cancelled, and Uplink grant NDI is used to indicate uplink retransmission.
  • the terminal device cannot distinguish the data reception status of the network device, that is, whether the retransmission is caused by the competition failure or by that the network device does not successfully demodulate the data.
  • the terminal device does not receive the acknowledgement message of the data packet, which may cause unnecessary upper layer protocol processing delay, such as the release of the data packet in the buffer. Therefore, a new method for feeding back HARQ information is needed, which can explicitly indicate feedback information of uplink data with respect to the terminal device.
  • US2016198453A1 discloses a method, device, and system for sending feedback information, to enable a receive end to transmit feedback information without using a PUCCH/PHICH feedback channel, so as to improve system efficiency.
